Long

Executive summary: it's 64 bits, or larger. unsigned long long is the same as unsigned long long int. Its size is platform-dependent, but guaranteed by the C standard (ISO C99) to be at least 64 bits. There was no long long in C89, but apparently even MSVC supports it, so it's quite portable. In the current C++ standard (issued in 2003), there is no long long, though many compilers support it as an extension. The upcoming C++0x standard will support it and its size will be the same as in C, so at least 64 bits. You can get the exact size, in bytes (8 bits on typical platforms) with the expression sizeof(unsigned long long). If you want exactly 64 bits, use uint64_t, which is defined in the header along with a bunch of related types (available in C99, C++11 and some current C++ compilers). @MichaelBurr 8 years later, I'm still questioning what I'm doing with my life, trying to figure out how to get as close as possible to what Rust does with it's forced type sizes at least from perspective of programmer who wrote out the literals, at compile time. Still no such luck. Things like this are nothing but pure agony. It must be at least 64 bits. Other than that it's implementation defined. Strictly speaking, unsigned long long isn't standard in C++ until the C++0x standard. unsigned long long is a 'simple-type-specifier' for the type unsigned long long int (so they're synonyms). The long long set of types is also in C99 and was a common extension to C++ compilers even before bei...

We don’t use long on its own in affirmative clauses. We often use ( for) a long time: We waited for a long time in the rain for the bus. Not: … waited long … They took a long time getting here. Not: They took long … We can use long in affirmative clauses with too, enough and so: A month is too long to wait for an appointment. We’ve waited long enough for a reply. I think we need to phone them. You took so long. What were you doing? When we talk about actual amounts of time, we can use phrases with time + long, or phrases like all day long, all month long: The lecture was three hours long. We worked all day long. We can also use a long time ago, long ago or long before to refer to a time many years in the past: This castle was built a long time ago. (or … was built long ago.) Long before you were born, there was a factory here. It was closed in the 1960s. We use long as an adjective: You’re home already. That can’t have been a very long film. Distance We can use the phrase a long way to talk about distance: My house is a long way from the station. You’ll have to take a taxi. It’s a long way to the nearest petrol station. In negative statements and questions we usually use far: My house is not far from the station. Is it far to the beach? About Ago Already Always Early Ever Hardly ever, rarely, scarcely, seldom Next No longer, not any longer No more, not any more Now Often Once Soon Still Then Usually Eventually Adverbs as discourse markers ( anyway, finally) Adverbs as shor...

long is the same as Int64 The ? means it is nullable A nullable type can represent the normal range of values for its underlying value type, plus an additional null value Nullable example: int? num = null; if (num.HasValue == true) This allows you to actually check for a null value instead of trying to assign an arbitrary value to something to check to see if something failed.

In this article Holds signed 64-bit (8-byte) integers ranging in value from -9,223,372,036,854,775,808 through 9,223,372,036,854,775,807 (9.2...E+18). Remarks Use the Long data type to contain integer numbers that are too large to fit in the Integer data type. The default value of Long is 0. Literal assignments You can declare and initialize a Long variable by assigning it a decimal literal, a hexadecimal literal, an octal literal, or (starting with Visual Basic 2017) a binary literal. If the integer literal is outside the range of Long (that is, if it is less than In the following example, integers equal to 4,294,967,296 that are represented as decimal, hexadecimal, and binary literals are assigned to Long values. Dim longValue1 As Long = 4294967296 Console.WriteLine(longValue1) Dim longValue2 As Long = &H100000000 Console.WriteLine(longValue2) Dim longValue3 As Long = &B1_0000_0000_0000_0000_0000_0000_0000_0000 Console.WriteLine(longValue3) ' The example displays the following output: ' 4294967296 ' 4294967296 ' 4294967296 Note You use the prefix &h or &H to denote a hexadecimal literal, the prefix &b or &B to denote a binary literal, and the prefix &o or &O to denote an octal literal. Decimal literals have no prefix. Starting with Visual Basic 2017, you can also use the underscore character, _, as a digit separator to enhance readability, as the following example shows. Dim longValue1 As Long = 4_294_967_296 Console.WriteLine(longValue1) Dim longValue2 As Long = &H1_000...

Calculator Use Divide two numbers, a dividend and a divisor, and find the answer as a quotient with a remainder. Learn how to solve long division with remainders, or practice your own long division problems and use this calculator to check your answers. Long division with remainders is one of two methods of doing long division by hand. It is somewhat easier than solving a division problem by finding a quotient answer with a decimal. If you need to do long division with decimals use our What Are the Parts of Division For the division sentence 487 ÷ 32 = 15 R 7 • 487 is the dividend • 32 is the divisor • 15 is the quotient part of the answer • 7 is the remainder part of the answer How to do Long Division With Remainders From the example above let's divide 487 by 32 showing the work. Divide 48 by the divisor, 32. The answer is 1. You can ignore the remainder for now. 48 ÷ 32 = 1 Note that you could skip all of the previous steps with zeros and jump straight to this step. You just need to realize how many digits in the dividend you need to skip over to get your first non-zero value in the quotient answer. In this case you could divide 32 into 48 straight away. Since 7 is less than 32 your long division is done. You have your answer: The quotient is 15 and the remainder is 7. So, 487 ÷ 32 = 15 with a remainder of 7 For longer dividends, you would continue repeating the division and multiplication steps until you bring down every digit from the divdend and solve the problem.
